I have great news for anyone who's doing the IB Diploma (I know a couple of you are, but I can't remember who)! SHAKE! counts as CAS! You can claim 60 hours for it if you attended for the whole 5 days and can prove what you've done and which group you were a part of.
You get 30 hours for Creativity and 30 for Action, which means nearly HALF of the requisite 150 wiped out in one week!
